Description
Technical field
The utility model belongs to compressor field, relates in particular to a kind of oil suction assembly of compressor.
Background technique
Compressor is the core component of air-conditioning, and the quality of its performance directly has influence on the quality of air-conditioning, and lubrication system is the important component part of compressor, and it carries lubricant oil to play effect lubricated and sealing to the interior special position of compressor.Because comprise a lot of relative movement friction components in the compressor, rotating speed is very high, and under harsh conditions, works, therefore the lubrication effect of lubrication system is had relatively high expectations.
The lubrication system of existing compressor comprises parts such as oil sump, oil pump, oil suction assembly and oil transport pipeline, and the oil suction assembly is sent the lubricant oil in the oil sump into oil transport pipeline under the effect of oil pump, and oil transport pipeline is transported to the special position in the compressor with lubricant oil.As shown in Figure 1, the oil suction assembly of existing compressor comprises assembly department 100 ＇ and fuel sucking pipe 200 ＇, and assembly department 100 ＇ upper end is communicated with oil transport pipeline, and the lower end is communicated with fuel sucking pipe 200 ＇; Fuel sucking pipe 200 ＇ lower ends are stretched into below the pasta, under the effect of oil pump, lubricant oil are sucked in the oil transport pipeline.Open Side Down owing to fuel sucking pipe, and the oil suction assembly of this structure is when work, and the fuel sucking pipe lower openings needs could guarantee that apart from oil sump bottom certain distance lubricant oil gets in the fuel sucking pipe smoothly.
As shown in Figure 2, when the compressor run-off the straight, the lubricant oil liquid level under the effect of gravity in the oil sump changes in the position of oil sump bottom; When compressor tilted to reach several angle, the fuel sucking pipe lower ending opening no longer was positioned at below the pasta, and lubricant oil and the oil feeding line in the oil sump no longer is communicated with at this moment; The kinetic friction parts of compressor can't continue to obtain the fuel feeding from oil sump; Thereby the initiation lubrication trouble influences the performance of compressor, even influences working life.
Compressor oil suction assembly of the prior art; Smooth and easy for guaranteeing oil suction; Must make fuel sucking pipe lower ending opening and oil sump bottom keep a segment distance, and assembly department is just fixing once installing, the bottom opening position of fuel sucking pipe can't be regulated; Be easy to when the compressor run-off the straight and the pasta disengaging, cause the lubricant oil failure of oil feed.
Usually the method for the injection amount of employing increase lubricant oil is avoided the generation of the problems referred to above; Can cause in the compressor operating process lubricant oil oil mass in the oil sump too much like this; And most of lubricant oil is not effectively utilized all the time, causes unnecessary waste, has increased cost.
The model utility content
When solving in the existing compressor operating process run-off the straight, the oil suction assembly separates with lubricant oil in the oil sump, causes the problem of failure of oil feed.
The utility model provides a kind of oil suction assembly; Comprise assembly department, said oil suction assembly also comprises oil-feed portion and flexible oil guide pipe, and oil guide pipe is communicated with said assembly department and oil-feed portion; Be provided with oil inlet passage in the said oil-feed portion; Said oil inlet passage comprises crosspassage and vertical passage, and said crosspassage is provided with filler opening in the side of oil-feed portion, and said vertical passage is communicated with crosspassage and oil guide pipe.
